Shared FDB allows to direct traffic from all the vports in the HCA to a single eswitch. In order to do that three things are needed. 1) Point the ingress ACL of the slave uplink to that of the master. With this, wire traffic from both uplinks will reach the same eswitch with the same metadata where a single steering rule can catch traffic from both ports. 2) Set the FDB root flow table of the slave's eswitch to that of the master. As this flow table can change dynamically make sure to sync it on any set root flow table FDB command. This will make sure traffic from SFs, VFs, ECPFs and PFs reach the master eswitch. 3) Split wire traffic at the eswitch manager egress ACL so that it's directed to the native eswitch manager. We only treat wire traffic from both ports the same at the eswitch level. If such traffic wasn't handled in the eswitch it needs to reach the right representor to be processed by software. For example LACP packets should *always* reach the right uplink representor for correct operation.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
